If you are wondering how to use Voicethread this will explain everything!
First thing you have to do is go to voicethread.com and click Create.Then you click Upload and 3 options will pop up,they will say my computer,media sources,and URL.Pick which one you prefer.
Then you click comment and you can use the crayon to mark on your photo and you can also explain by talking into your mic on your headphones.
This can help you in school in many ways.Such as how I used it for my Geography class.
Go to my blog and observe how your voicethread could look.
